Microsoft AI Achieves Highest Ms. Pac-Man Score Possible

The video game world recently witnessed Ms. Pac-Man history: For the first time, the game’s maximum score of 999,990 points has been reached. As Business Insider reports, the landmark wasn’t achieved by a competitive gamer but rather an AI algorithm owned by Microsoft.

After the AI start-up Maluuba was acquired by Microsoft in January, one of their first orders of business was developing a system capable of running through the Atari 2600 version of Ms. Pac-Man with more efficiency than any human player. To do this, they set up a program that rewarded the AI for completing different tasks like dodging ghosts and eating fruit. Each accomplishment was assigned a certain value, allowing the algorithm to prioritize problems as they arose. You can learn more about the strategy behind the win in the video below.

The game ended when Ms. Pac-Man racked up 999,990 points, the highest number the game can reach before resetting to zero. According to highscore.com, the previous Atari 2600 Ms. Pac-Man record of 266,330 belonged to a man from Brazil. Though it isn’t the most popular version of the title, researchers chose to play on the Atari 2600 game because the console has become standard for AI projects across the field. The maximum score on the original Ms. Pac-Man game, however, is still up for grabs.

Researchers in Singapore Deploy Robot Swans to Test Water Quality

There's something peculiar about the new swans floating around reservoirs in Singapore. They drift across the water like normal birds, but upon closer inspection, onlookers will find they're not birds at all: They're cleverly disguised robots designed to test the quality of the city's water.

As Dezeen reports, the high-tech waterfowl, dubbed NUSwan (New Smart Water Assessment Network), are the work of researchers at the National University of Singapore [PDF]. The team invented the devices as a way to tackle the challenges of maintaining an urban water source. "Water bodies are exposed to varying sources of pollutants from urban run-offs and industries," they write in a statement. "Several methods and protocols in monitoring pollutants are already in place. However, the boundaries of extensive assessment for the water bodies are limited by labor intensive and resource exhaustive methods."

By building water assessment technology into a plastic swan, they're able to analyze the quality of the reservoirs cheaply and discreetly. Sensors on the robots' undersides measure factors like dissolved oxygen and chlorophyll levels. The swans wirelessly transmit whatever data they collect to the command center on land, and based on what they send, human pilots can remotely tweak the robots' performance in real time. The hope is that the simple, adaptable technology will allow researchers to take smarter samples and better understand the impact of the reservoir's micro-ecosystem on water quality.

This isn't the first time humans have used robots disguised as animals as tools for studying nature. Check out this clip from the BBC series Spy in the Wild for an idea of just how realistic these robots can get.

Stop Your Snoring and Track Your Sleep With a Wi-Fi Smart Pillow

Everyone could use a better night's rest. The CDC says that only 66 percent of American adults get as much sleep as they should, so if you're spending plenty of time in bed but mostly tossing and turning (or trying to block out your partner's snores), it may be time to smarten up your sleep accessories. As TechCrunch reports, the ZEEQ Smart Pillow improves your sleeping schedule in a multitude of ways, whether you're looking to quiet your snores or need a soothing lullaby to rock you to sleep.

After a successful Kickstarter in 2016, the product is now on sale and ready to get you snoozing. If you're a snorer, the pillow has a microphone designed to listen to the sound of your snores and softly vibrate so that you shift positions to a quieter pose. Accelerometers in the pillow let the sleep tracker know how much you're moving around at night, allowing it to record your sleep stages. Then, you can hook the pillow up to your Amazon Echo or Google Home so that you can have your favorite smart assistant read out the pillow's analysis of your sleep quality and snoring levels the next morning.

The pillow is also equipped with eight different wireless speakers that turn it into an extra-personal musical experience. You can listen to soothing music while you fall asleep, either connecting the pillow to your Spotify or Apple Music account on your phone via Bluetooth or using the built-in relaxation programs. You can even use it to listen to podcasts without disturbing your partner. You can set a timer to turn the music off after a certain period so you don't wake up in the middle of the night still listening to Serial.

And when it's time to wake up, the pillow will analyze your movements to wake you during your lightest sleep stage, again keeping the noise of an alarm from disturbing your partner.

The downside? Suddenly your pillow is just another device with a battery that needs to charge. And forget about using it in a place without Wi-Fi.

The ZEEQ Smart Pillow currently costs $200.
